A phase-shift oscillator is an oscillator circuit designed to generate a sinewave output. It operates with a single active element such as a BJT or an op amp configured in an inverting amplifier mode. The circuit arrangement creates a feedback from the output to the input through using an RC (resistor/capacitor) circuit arranged in a […]

500 Watt Inverter Circuit with Battery Charger
In this post we will comprehensively discuss how to build a 500 watt inverter circuit with an integrated automatic battery charger stage. Further in the article we will also learn how to upgrade the system for higher loads and how to enhance ot into a pure sine wave version. This 500 watt power inverter will […]
Reed Switch – Working, Application Circuits
In this post I will comprehensively explain about reed switch functioning, and how to make simple reed switch circuits. What is Reed Switch Reed switch also called reed relay, is a low current magnetic switch with a concealed pair of contacts that close and open in response to magnetic field near it. The contacts are […]
Comparator Circuits using IC 741, IC 311, IC 339
The basic function of a comparator circuit to compare two voltage levels at its input pins and produce an output to show which input voltage has higher potential than the other. In this article we will elaborately learn how to correctly design comparator circuits using popular ICs like IC 741, IC 311 and IC LM339 […]
CMOS IC LMC555 Datasheet – Works with 1.5 V Supply
In this post we study the datasheet, pinout, and technical specifications of the IC LMC555 which is a CMOS version of the standard IC 555. The IC is equipped with many outstanding features, the most amazing being its minimum supply range which is down to 1.5V. Meaning now you have an IC 555 which can […]
High Current Zener Diode Datasheet, Application Circuit
Zener diodes that are normally available are mostly 1/4 watt or 1/2 watt types. And it is quite valid since the basic function of zener is to create stabilized reference voltage. Zener diodes are not designed for current regulation directly. However, for some applications where shunting excess voltage and current is necessary a high current […]
